Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a floating connector. Background Art

[0002] Connectors are a component that our electronic engineering technicians often come into contact with. Connectors are widely used in various line connections. Their function is very simple: to build a bridge of communication between blocked or isolated circuits within a circuit, so that current can flow and the circuit can achieve its intended function.

[0003] At present, the battery cells and busbars in the energy storage cabinet are connected by connectors, but processing and assembly will bring tolerances, and there will inevitably be position deviations between the connector and the busbar. When the battery cell is inserted into the busbar, the plastic of the connector may collide with the busbar due to position deviation, causing the connector to be damaged. Even after insertion, the position deviation may cause excessive contact of the terminals on one side of the connector, causing the terminals to yield, and the contact on the other side may be unstable. In extreme cases, there will be unilateral contact. In pursuit of reliability, more and more customers will pursue blind insertion of battery packs to contact the busbar.

[0004] Therefore, we propose a floating connector to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a floating connector to solve the problems raised by the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a floating connector, comprising a plastic shell, a contact assembly is installed in the inner cavity of the plastic shell, and a back cover is arranged on one side of the inner cavity of the plastic shell.

[0007] Preferably, the contact assembly includes a rubber core sleeved in the inner cavity of the plastic shell and a metal plate with one end extending into the inner cavity of the rubber core, and spring terminals are respectively arranged on one side of the top and bottom of the metal plate, and the spring terminals are engaged in the inner cavity of the rubber core.

[0008] Preferably, grooves are respectively provided at one side of the top and the bottom of the rubber core, and the inner cavities of the grooves are respectively provided with stainless steel arch bridge pieces.

[0009] Preferably, the stainless steel arch bridge member is vertically symmetrically arranged with the central axis of the rubber core as the opposite axis, and the arrangement of the stainless steel arch bridge member is used to position the rubber core in the center.

[0010] Preferably, the metal plate and the spring terminal are connected via rivets respectively.

[0011] Preferably, the spring terminal is respectively provided with a plurality of slots, and the arrangement of the slots is used to make the spring terminal elastic.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting the contact component of the connector to float, the position of the contact component can be automatically adjusted according to the position of the bus. This can absorb the position deviation between the connector and the bus, allow the connector to be safely inserted into the bus, and ensure stable contact between the bus and the connector terminal.
